Finding out-of-date systems

A more elaborate way is to iterate through all systems and find their status

spacecmd -u admin -p admin system_list

and then

spacecmd -u admin -p admin system_listerrata <system>

for every system

The main difference between 'report_outofdatesystems' and 'system_listerrata' is that the former works on package updates while the latter works on patches. Patches provide additional information about package updates (i.e. if the update contains a security-relevant fix), but are not always available (i.e. for in-house repositories containing only packages).
